Laser Beam Couplers Series 60SMF-LSA
The Schäfter+Kirchhoff laser beam couplers launch a laser beam into, or from a polarization-maintaining
single-mode fiber. This document provides assistance in installing and adjusting the laser beam couplers
series 60SMF-LSA. It describes how a fiber cable is attached, and how a fiber coupling is optimized.
1. Before You Start
The laser beam coupler is shipped with a protection cap for the fiber receptacle and with a front cap.
Please remove all the protection caps first and do not use them as beam
dumps (risk of photo contamination).
Notice:
There is a polymer cap on the receptacle. Please perform the following steps in order to remove this cap:
Figure 1:
First, remove the cap from the fiber
receptacle of the laser beam coupler.
Figure 2:
Then, slightly loosen the small pin
screw. Use the screwdriver 9D-12.
Make sure to not loosen it too far, as it
is small and easily lost.
Now, make sure that the connector of the fiber you want to attach matches the receptacle type of the laser
beam coupler:
•
Use fibers with APC (8°-polish) connectors for laser beam couplers with an inclined coupling axis
(60SMF-LSA-4).
•
Use fibers with PC (0°-polish) connectors for laser beam couplers with a coaxial axis
(60SMF-LSA-0).
The laser beam couplers are compatible to all fiber connectors of type LSA, DIN, AVIO and AVIM.
